摘　　要：本文对国内最新研制的256×1元GaN基紫外探测器的原理和特点进行了分析与介绍,研究了对应的信息获取原理与方法,完成了信息获取系统的设计与实现,阐述了基于256×1元GaN基紫外探测器的便携式紫外线阵相机的设计过程,完成了相机信噪比测试和外景成像试验。通过与海洋相关研究所合作,实地进行了相机的出海搭载试验,成功获取了海面的紫外图像数据。实验结果表明:海面图像清晰,纹理丰富,为相机便携出海作业和海洋环境监测应用做出了探索性的工作。It was analyzed that the principle and characteristics of a GaN-based Ultraviolet （UV） detector developed recently by Chinese, and that the principle and method of the information acquisition technology for the detector is achieved. It was described that the design process of portable UV camera with the GaN-based UV detector. The Signal-to-Noise Ratio （SNR） of the camera and the outdoor experiment were finished. Through the cooperation with the Marine-related institute, the portable camera was mounted on the research vessel and the UV image of the sea surface was successfully acquired. The results show that the image of the sea surface is clear and rich texture, which made a maiden attempt and explorations of UV remote sensing detections to the marine oil spill.
